no blanks; the last name may well contain upper case and
blanks for readability.
+ Lines beginning with a `#' in the first column are treated
+ as comments. While comment lines are legal at any point,
+ the output of <EM>captoinfo</EM> and <EM>infotocap</EM> (aliases for <EM>tic</EM>)
+ will move comments so they occur only between entries.

+ Newlines and leading tabs may be used for formatting

+ if-then-else expressions: the result can be read by <EM>tic</EM>.

Terminal names (except for the last, verbose entry) should
be chosen using the following conventions. The particular
piece of hardware making up the terminal should have a
vt100-w. The following suffixes should be used where pos-
sible:
+
<STRONG>Suffix</STRONG> <STRONG>Meaning</STRONG> <STRONG>Example</STRONG>
-<EM>nn</EM> Number of lines on the screen aaa-60
-<EM>n</EM>p Number of pages of memory c100-4p

-s Enable status line vt100-s
-vb Use visible bell instead of beep wy370-vb

Capabilities in <EM>terminfo</EM> are of three types: Boolean capa-

- ular feature, numeric capabilities giving the size of the
- terminal or the size of particular delays, and string
- capabilities, which give a sequence which can be used to
- perform particular terminal operations.

If the environment variable TERMINFO is set, it is inter-
preted as the pathname of a directory containing the com-
beginning of the next line when it reaches the right mar-
gin, then it should have the <STRONG>am</STRONG> capability. If the termi-
nal can clear its screen, leaving the cursor in the home
- position, then this is given by the <STRONG>clear</STRONG> string
- capability. If the terminal overstrikes (rather than
- clearing a position when a character is struck over) then
- it should have the <STRONG>os</STRONG> capability. If the terminal is a
- printing terminal, with no soft copy unit, give it both <STRONG>hc</STRONG>
- and <STRONG>os</STRONG>. (<STRONG>os</STRONG> applies to storage scope terminals, such as
- TEKTRONIX 4010 series, as well as hard copy and APL termi-
- nals.) If there is a code to move the cursor to the left
- edge of the current row, give this as <STRONG>cr</STRONG>. (Normally this
- will be carriage return, control M.) If there is a code
- to produce an audible signal (bell, beep, etc) give this
- as <STRONG>bel</STRONG>.
-
- If there is a code to move the cursor one position to the
- left (such as backspace) that capability should be given
- as <STRONG>cub1</STRONG>. Similarly, codes to move to the right, up, and

+ ity. If the terminal overstrikes (rather than clearing a
